The solution
Detail solution
Given the linear equation:
Move free summands (without y)
from left part to right part, we given:
$$12 y = 2 y - 10$$
Move the summands with the unknown y
from the right part to the left part:
$$10 y = -10$$
Divide both parts of the equation by 10
We get the answer: y = -1
12*y+3 = 2*y-7
Move free summands (without y)
from left part to right part, we given:
$$12 y = 2 y - 10$$
Move the summands with the unknown y
from the right part to the left part:
$$10 y = -10$$
Divide both parts of the equation by 10
y = -10 / (10)
We get the answer: y = -1
